Abstract Effect of irradiation on corrosion of 304 nuclear grade stainless steel (304NG SS) in simulated primary water of pressurized water reactor was investigated. The investigation was conducted by comparing the microstructure of the oxide scale formed on the steel irradiated to different doses by proton. The results revealed that increasing irradiation dose promoted both the corrosion and intergranular corrosion of 304NG SS. This is attributed to the irradiation induced defects as well as the Cr depletion at the grain boundary in the steel.

辐照对模拟压水堆原水中304核级不锈钢腐蚀的影响

摘要 研究了辐照对304核级不锈钢(304NG SS)在压水堆模拟一次水中腐蚀的影响。研究是通过比较不同剂量质子辐照的钢上形成的氧化皮的微观结构来进行的。结果表明，增加辐照剂量促进了 304NG SS 的腐蚀和晶间腐蚀。这归因于辐照引起的缺陷以及钢中晶界处的 Cr 消耗。
